The separator contains thermocamera formed by the housing and cover. Inside thermocamera posted by bellows hermetically connected to the upper side of the flange, and the bottom with its own bottom and restrictive valve. The valve consists of a piston rod and piston and closes the openings for the fluid. Thermocamera has at least two holes for venting. Inside of the bellows placed the pipe, the distance from which to the bottom of the bellows is slightly greater than the length of the stroke restrictive valve. The valve is connected coaxially with the bottom of the bellows outside it. The technical result is increased reliability of the separator. 2 C.p. f-crystals, 1 Il. The invention relates to the field of creating and measuring pressure and may find application in instrumentation, petrochemical and other industries.Known separating device for measuring pressure , consisting of a body and placed it bellows, forming two insulating cavity, one of which is connected with a calibrated pressure gauge and the other with the GRU is rolling contact with the core winding of the potentiometer, the winding of the solenoid is connected to the power source through a potentiometer.A disadvantage of this device is that the bellows has no restrictions under compression, thus can occur deformation of the bellows. Then, when the pressure measurement will be a large error.It is known device , consisting of thermocamera formed by the casing and a lid, the lid and the bottom has openings for the supply of the environments inside the body is placed nozzles for supplying these environments connected by one end with the feed holes, while equipped with at least two holes for exhaust air cover is made in the form of a Cup with flanges, with one hole for exhaust air is located in the flange, and the other in the bottom cover, the upper end of the pipe, making the environment with a lower specific gravity, is located above the top edge of the hole for exhaust air located in the flange.A disadvantage of this device is that it is not sufficiently reliable in operation, as the oil can get into the test device.The prototype of the present invention is a separator device for calibration of oxygen gauges  , consisting of a camera bellows to limit the exemplary dead weight pressure gauge. The coil ends fitting to attach oxygen gauges. The inlet tube is connected to the manometer by means of a nut with an internal cavity of the bellows.The disadvantage of the prototype is that the bellows under pressure is stretched, that is, the stroke is 30% of the maximum stroke of the bellows.The aim of the invention is to improve the reliability of the separator when using it.This objective is achieved in that the separator hydraulic bellows is thermocamera formed by the housing made in the form of a Cup and cover, placed inside the bellows is hermetically connected to the upper side of the flange, and the bottom with its own bottom, inside of the bellows placed the pipe, the distance from the nozzle to the bottom of the bellows is slightly greater than the length of the stroke bounding valve, the valve consisting of a piston rod and piston, closing the holes for the oil inlet, is connected coaxially with the bottom of the bellows, made in the form of a hollow cone, thermocamera have not less than two holes for exhaust air. The separation medium are water and oil, alcohol, or oil, or other liquid, not corrosive to stainless steel, brass.Silvana, inside of the bellows entered the pipe to prevent oil in the calibrated gauge. Is restrictive valve in the lower part of the housing and connected to the bottom of the bellows, made in the form of a hollow cone. Dead weight pressure gauge and checked the device can be connected directly to the separator.On Cherie shows a General view of the separator hydraulic bellows RGS-6.The separator consists of thermocamera formed by the housing 1 and the cover 2, in which there is a hole 3 for the connection of dead weight pressure gauge and the hole 4 to connect a calibrated pressure gauge. On thermocamera there are openings 5 and 6 for the exhaust air. Inside between the housing and the cover 2 is placed bellows 7, the inside of the bellows has a built-pipe 8. Outside, to the bottom of the bellows, made in the form of a hollow cone 9, attached restrictive valve 10.Separator hydraulic bellows operates as follows.After filling systems for the liquids close the openings 5 and 6. The 4 hole joining verified the device, in this case, the oxygen gauge. Then with the help of the press, is connected to the hole 3, is created in the pressure. When the bellows 7 is compressed and brassavola gauge. In case of water leakage (alcohol) from the camera, the bellows is compressed to the maximum length, and then bounding the valve 10 closes the entrance into the cavity of the camera. A further increase in pressure in the bellows does not apply.Literature
